' Application filed September 21, 1925. Serial No. 57,636.

This invention relates to the method of and apparatus fortheconstruction of glued ends for packing boxes. such asare .described inthe copending'application of V Clement A. Brown and ClydeA. Batchelder,

- ,filed January 19,. 1925 ,"Serial Number 3,306,

fruit box.

In thepacking of fruit, vegetables, and

V thelike, packing boxes are employed Which are. constructed of WOOCl.The construction 7 of these packing boxes must be such that the same areof light Weight butnareof sturdyconstructionto enable them to Withstandthe handling received during the ship- -5 ping thereof. The end membersemployed in the construction of these boxes have been and are at presentin many instances formed of, single portions of Wood Which areexpensiveand diflicultfto'obtainin the sizes required for theconstruction of the boxes and as the supply of Wood becomes more orlesslimited in any particular locality it, be comes more difficult toobtain Wood of suf-' ficient Width to-prepare or form the end sectionsofsingle-portions there0f, and alvso as the supply of Wood in anyparticular locality becomes diminished, the quality of the WOOCllikewise decreases so that it isex- Y tremely difiicult to obtain singlepieces of box ends Which are not of such inferior quality that the same,on being employed for the construction'of boxes, Will split when nails,staples, or the like, are driven into the :15 same during theconstruction of the boxes. j A box end constructed in accordance withthe disclosure in the I'application for fruit box, 'Ser. No. 3,306,"above referred to, is

- extremely ell adapted totake the placeof tion and-greater reliabilityand durability in that the same eliminates the liability of splitting.

4n "It is an object of this invention tofprovide 'a method ofconstruction of 'the box ends. constructed of a plurality of relativelynarwood of great enough Width to prep-are these a single portionofvvoodbox ends hereto .fore employed, and is of cheaper construetion ofpacking boxes.

F ig. 5 is a perspective plan viewoffa completed'glued boxend constructed in accordance .With' the processfembodying thisinvention. V I a r .In. the preferred embodiment of this inventionillustrated in the accompanying drawings, theapparatus includes meansfor v ect of this inventionis to provide an apparatusflfor carrying outthe proccutting and squaring strips of m'aterialll which means'comprisea guideway 2 upon Which aplurality of strips" of material 1 are placed,which strips of material are of greater length, and their'combined idthis greater than the idth, required for. the

box end; A. guide rail 3 is secured to the guidevvay 2 and guides'thestrips of'mate'rial at one edge thereof. A pusher block 4 is l mountedin theguideway to engage the rear- I Ward edge of the strips ofmat'eriall. A

slide block 5 is mounted in a'slot G formed Y "in the guide'way 2 andsupports thestrips of material 1 during their travel alongthe guideW-ay2.

, Th -operator grasps the handle? the i i pusher block 4 and causes thestrips of material 1 to move along the guide ay'QI pasta rotating savv'8which saw acts to cut the strips of the material to the proper yvidth.

The rotating saw 8 is of any desired or preferred construction andmanner of operation, and is herein illustrated as secured to a shaft 9at a co la-r 10 which shaft 9 is also rigidly secured to a belt pulley11 which belt pulley 11 may be driven through auxiliary pulleys 12through a belt connection from a drive shaft 13. The pusher block aiscut away, as illustrated at 14, to permitthe strip of maperial 1 withoutcutting the for ward engaging edge of the pusher block 1. The strips ofmaterial 1 are then advanced to the position illustrated at B over asecond runway 1 where the same are engaged 'by'means of a pusher block16 and con veyed along tl e slide 1? mounted in the slot 18 past a pairof saws 19 where the strips of material 1 are cut tothe proper lengthand squared at their ends. The saws 19 are secured to shafts 20 atcollars 21 to whlch shafts 20 pulleys 22 are secured,

which pulleys 22 are driven by belts from the drive shaft 13.

The strips of material 1, having been properly cut and squared, areadvanced along the runway 15 to the position C. The strips of material 1are now ready to be glued to and hold the reinforcing and holding stripsor cleats 23.

-For gluing the strips of materials 1 to the reinforcing strips'23, Iprefer to employ the following means:

A plurality of such cleats 23 are mounted in a magazine 2 1 adjacent aglue pot 25, four of such cleats 23 being mounted side by side, thecleats 23 having been'previous- 1y formed to the correct length andwidth for the formation of the box ends and for gluing to the two endsof the strips of material 1, the pusher block 26 is mounted ona platform27 in position to eject the cleats 23 from the magazine The pusher block26 is pivotally connected at a pin 23 to a link 29 which link 29ispivotally connected at a pin 30 to a rocker arm 31, which is pivotallyconnected at its opposite end at'a pin 32 to the stationary member 33.The rocker arm 31 is pivotally connected interl'l'lGCllfitfiltSEllClS ata pin 34; to a rod 35, which rod 35 ispivotally connected at a pin 3t tothe operating lever 37, which is angled at its lower end to form a footpedal38. The operating lever 3? is pivotally connected at apin 39 to asecond stationary support 40. In order to hold the pusher block 26 inthe ejecting position, a weight 11 is connected to a cable 42 which istrained over a pulley 43 and is secured to the outer end of the link 29.The pulley is rotatably supported in a bracket 44 secured to theframework of the apparatus.

An operator stepping on the foot pedal 38 causes four cleats 23 to bemoved under the discharge spout 4:5 of the glue pct 25 saw 8 to cutthrough the outer ti oned.

and to receive glue on their upper surfaces. A portion of felt or othermaterial 16 is mounted in position to remove the surplus glue from thesurfaces of the cleats 23. In order tosecurely hold the strips ofmaterial 1 in engagement with the cleats 23 during the gluing of thecleats 23 to the ends of the strips 1, a gluing frame 17 is providedwithin which a plurality of boX ends vmay be formed. The gluing frame l?is herein illustrated as being formed to accommodate two such box ends.Howevenit is to be understood that anysuitable or desirable number ofbox ends may be glued in such a gluing frame M.

The operator-having ejected four cleats 23 from the magazine 24 past thegluing pot .25,takes these cleats 23 and. positions one of them as at48. The strips 1 having been properly squared and out are then movedfrom the positionC to the position D where their ends are in engagementwith the glued surface of the cleat 23. A second cleat 23, having glueon its engaging surface, is then positioned at 19. A third cleat is thentaken and positioned with its glued surface away i from the cleat 23into the position 49. A second group of strips 1 are then moved intoposition toengage the last mentioned cleat 23. The last cleat 23' of thegroup is then taken by the operator and applied to the outer surface ofthe lastgroup of strips 1 in the position illustrated atin Fig. 4:. p

The gluing frame 47 is then moved to position in the clampingapparatus51 which clamping apparatus 51 is preferably of the followingconstruction and operation:

The gluing frame 4:? has slots-52 at its outer ends into which aclamping wedge 53 is adapted to be forced with its straight edge inengagement with the cleat 23 which is in the position 50. The oppositeedge 55 V of the wedge 53 is tapered for a purpose that will hereinafterappear. Theclampapparatus 51 comprises a platform 56 onto which theclamping frame 17 is posii hold-down plate 57 is mounted in position sothat the same may be engaged with the upper surface ofthe strips 1 tohold the same from buckling during the clamping operation. The hold-downplate 57 is pivotally secured at the -pin,58 to a link 59 which link 59is pivotally supported at its opposite end at a pin 60 to a rocker arm61, which rocker arm is pivotally sup ported at a pin intermediate itsends at a'p-in 62 in a bracket 63 secured to the frame of the apparatus.The rocker arm 61 is pivoted at apin 64: to a link 65 which link 65 ispivotally secured at its opposite end at a pin 66 to an operating pedal67, which operating pedal is pivotally supported at a pin 68 mounted in.a standard 69. V

A weight 70 is secured to the rearward in a standard"77'.

end of the operating pedal67 so as to ndr-f (not shown) is mountedtoreciprocateand' which piston is I connected by means of a piston rod 74 at a pin 75 to an arm 76*Whl0l1 ispivotally supported at a pin 6"mounted v The arm 76 is pivotally' supported at its opposite end 7 8toaconnecting link 79 whiohis pivotally connected at a'pin'SO to awedge-engaging member 81,

which'wedgeengaging member 81 is pivotally supported at itslower end ata pin 82' to a standard, 83. The wedge-engaging member 81 v is guided ina guideway'84so as tribe in position to'engage at its forward edge 85the outer end of the wedge 53. The

wedge-engaging member 81 engages the.

wedge 53 and causes the sameto be forced through the slots.52 so as toclamp the'strips 1 of the material in engagement with the respectivecleats 23.] After the wedge 53 has'been properly forced into positionthe operator releases the pedal 67 and permits the engaging plate 57 toraise from engagement with the members 1 and 23 and clamping frames? islifted'fromthe platform 56 and set aside to permit the glue to harden toproperly unitethe member 1 and 23.

From the foregoing, it will be apparent that my method or processconsists-in" the steps of first, forming thestrips'of material to theirproper width second, forming the strips ofmaterial to their properlength;

third, positioning the strips'of material in engagement with reinforcingcleats in a gluing frame; and 4, wedging or gluing the strips ofmaterial and the reinforcing cleats inengagement to permit the glue toharden to unite the same.

Having fully described a 'preferre'd'embodiment of this invention, it"is to be understood that it is not intended thatthe same should belimited to the exact details herein set forth which may,obviously, bearied E5 in detail without departing from the spirit of the invention asset forth in the appended claims.
